It is one of the objects of the invention to utilize a casing to encase the means whereby same is rotated, and to employ this casing as a winding drum for raising and lowering an object.

The invention has as a further object a provision whereby the device as awhole may be actuated and transported by the same mechanism which causes the rotation of the winding drum, to cause its travel from one place to another.

It is a further objectto permit the drum to be rotated independently of the transporting mechanism so that an object may be raised or lowered to the desired height and be held suspended, permitting the device with its load to be positioned at any desired The arrangement resorted to for accomplishing this rotation of the drum and actuation of the device as r a whole, considerably augments the power of the motor, thus demanding only the use of a comparatively small motor to accomplish the end sought to be attained.

It is an object of the invention to accomplish these and other results in a simple and expeditious manner. v

The invention will be explained in detail with reference to the accompanying drawifigs, in which one embodiment thereof is illustrated and in which Fig. 1 is a side elevation of the device arranged for use; 7

Fig. 3 is an enlarged sectional view taken on line 3-3 of Fig. 2;

Fig. 4 is a section taken on line 4-4 of ig. 5 1s a detail of a brake mechanism which may be employed showing some of the parts ina changed position. The invention is illustrated as applied to that type of these devices, which travels along rails or tracks arranged transversely to each other, so that the device may be positioned to receive or de osit an object at any desired place below t e tracks. The invention is not confined to the particular adaptation in which it is shown, as the idea of utilizing the casing of the driving mechanism as a drum for the hoisting cables is applicable to devices other thanthat illus trated inthis embodiment of the invention.

The invention will be explained in conjunction with the type of apparatus shown which employs suitably arranged rails 10 (only one bemg shown), upon which rides the bridgestructure generally designated 11 having the wheels 12. This bridge structure is provided with the rails 13-13 arranged transversely to the rails 10. The truck or trolley let which carries the hoisting apparatus is arranged upon these .rails 13-13, and is provided with the wheels 15-16 arranged at opposite ends of the truck. These wheelsca-rry a framework 17 upon which is mounted the motor 18, winding drum 19, and other elements of the device. The motor 18 is connected with the source of power in any suitable or convenient manner, and is in turn connected with the hoisting drum 19 as by the sprockets 20 and 21, and chain connection22l The sprocket 21 is permanently secured to the shaft 23 which extends into the casing of the drum 19 and is journaled in, oneend thereof. A shaft 24 is also journaled in the casing but in the opposite end, and protrudes therefrom. This shaft is provided with the brake drum 25, and the sprocket 26, "whichlatter 'is connected by the sprocket chain 27 to the sprocket 28 which in turn is connected .to the shaft 29 of the wheels 15. This last named shaft and connection form the means for transmitting the power from brake drum 33 which is controlled by a suit able brake mechanism hereinafter to be described. The brake drum 25 is also provided with a brake which may be of a struc- 5 ture similar'to that employed in connection with the brake drum The shafts 23 and 24 are loosely arranged with respect to the casing or hoisting drum 19, but are connected with the casing by the reduction gear structure generally designated 34 which is arranged within the casing 19. This gear mechanism may be caused to either rotate the casing 19 or operate themeans whereby the truck is actuated to cause it to travel structure shown in Fig. 3 includes a pinion 36 which is made fast to the shaft 23. A pair of gears 37 and 38 mesh with the pinion and in turn mesh withthe internal gear 35 which is made fast with the casing 19. The gears 37 and 38 are mounted upon shafts 39 between rotary members 40 and 41. The member 40 is journaled upon the extension 47 of the plate 30 and the plate 41 is arranged to rotate upon the shaft 24. The, plate 41 has a pinion 43 which is arranged between and meshes with the gears .44 and 45 which in turn mesh with the internal gear 46 which is also made fast to the casing 19. These gears 44 and 45 are mounted upon shafts 47 --47 which project from the member 48. This member 48 is also loosely mounted to rotate about the shaft 24, and is provided,

with a pinion 49 similar to the pinion 43 of the member 41. The pinion 49 meshes with the gears 50 and 51. which in turn mesh with the'internal gear 52 in the same manner as gears 37, 38, 44 and 45 do with their respective internal gears. These gears 50 and 51 shafts 54. This last named plate or member 53 is secured to the shaft 24 by the key 55.

This causes this shaft to be rotated by the internal'gear mechanism when the shaft 23 is actuated and the shell 19 is held. The

' gear ratio illustrated in the drawings re sults in that theshafts 23 and 24 are rotated at relatively different speeds, which naturally result in-that a relatively greater power will be derived from one shaft than from the other.

As before stated each of the brake drums 25 and 31 is provided with a suitable brake brakes. along the rails 1313. The particular. gear are mounted upon the member 53 by the The particular arrangement for,

ment 61 composed of the clips 62 and 63 is.

utilized, these clips 62 and 63 are connected together by the rotatable threaded bar 64, which may be operatedto take up the wear between the parts and the wear of the lining 57. The rods are each connected to the lever 60 which may be operated and held in either of its positions to hold or release the Normally either one or the other of these brake devices is applied to its respective drum as 25 or 33, depending upon whether the hoisting apparatus or the truck which carries the hoisting apparatus is to be operated. Should the operation of the hoisting apparatus be desired, the brake of the drum 25 will be applied. This holds the shaft 24 against rotation, causin all 'of the force to be applied to the caslng 32, which consequently rotatesit raising or lowering the object to be carried. By the application of the brake 33, the drum will be held against rotation and the object held in suspension. The direction in which the casing is rotated is dependent upon the direction in which the motor is driven, it being understood that a motor of the type that can be rotated in either direction is employed, although any suitable reversing mechanism may be employed in its stead. When the truck is to be moved or caused to travel, the drum 32- will be held against rotatlon, by the application of the brake which cooperates with the brake drum 33 and the brake which holds the brake drum 25 released. This causes all of the force to be applied to the shaft 24, rotating it, and by virtue of the connection between the shaft 29 and the shaft 24 causes the truck to travel along the tracks of the bridge structure, carrying with it the cage or platform A, in which the operator is stationed.

By referring to Fig. 3 and assuming that the casing 19 is held against rotation, it can readily be seen that as the shaft 23 and pinion 36 are rotated the gears 37 and 38 will also rotate, and by virtue of their engagement with the internal gear 35, which is part of the casing, causes the gears 37 and 38 to revolve about the shaft 23 as a center. The movement of these gears 37 and 38 around the shaft 23 rotates the plate 41 which causes motion to be imparted to it and its pinion 43, which is integral therewith, causing the gears 44 and 45 to rotate and the member 48 to revolve. The pinion 43 causes the gears 50 and 51 and the member 53 to be actuated ina manner similar to the elements of a like nature. By virtue of the fact that the member 53 is. keyed to the shaft 24, this shaft with its associated'parts is caused to rotate. When the shaft 24 is held against rotation the drum 19 is rotated. Under these conditions the gears 37 and 38 are rotated and the member 41 revolved. This naturally causes the actuation of the pinion 43, gears 44 and 45, member 48 and pinion 49. and by virtue of the fact that the member 53 is held, the force of the pinion 49 is transmitted to the internal gear 52 which is fast with the casing 19. During the rotation of the casin the gears 37, 38, 44 and 45 assistin actuating the drum 19.

The arrangement also may be operated so as to wind the cable upon the drum and at the same time cause the truck to travel along its rails. This may be accomplished by retarding the rotation of the drum 25. This will retard the portion 53 sufiiciently to turn the drum 19 and also permit this portion 53 to rotate the shaft 24.

From the foregoing it can readily be seen that the hoisting drum may be operated independently of the shaft 24 and also that this shaft and drum may be operated together.

Whereas the invention is shown as arranged to drive the truck along its track, it is evident that any other suitable device may be driven from this portion instead, also that the truck may receive its motive force from the device in many ways other than shown without departing from the spirit of the invention.

Having shown and described one embodiment of the invention, it is obvious that modifications may be resorted to without departing from the scope of the appended claims.
